Python Pandas - 返回一个索引，其中包含表示 IntervalArray 中每个 Interval 长度的条目
要返回包含表示IntervalArray中每个Interval长度的条目的索引，请使用array.length属性。
首先，导入所需的库-
import pandas as pd
创建两个Interval对象。使用值为“both”的“closed”参数设置的闭合区间-
interval1 = pd.Interval(50, 75, closed='both') interval2 = pd.Interval(65, 95, closed='both')
从Interval对象构造一个新的IntervalArray-
array = pd.arrays.IntervalArray([interval1,interval2])
显示IntervalArray-
print("\nOur IntervalArray...\n",array)获取IntervalArray的长度。返回一个索引，其中的条目表示IntervalArray中每个Interval的长度-
print("\nOur IntervalArray length...\n",array.length)示例
以下是代码-
import pandas as pd
#CreatetwoIntervalobjects
# Closed intervals set using the "closed" 带值的参数 "both"
interval1 = pd.Interval(50, 75, closed='both')
interval2 = pd.Interval(65, 95, closed='both')
#displaytheintervals
print("Interval1...\n",interval1)
print("Interval2...\n",interval2)
#displaytheintervallength
print("\nInterval1 length...\n",interval1.length)
print("\nInterval2 length...\n",interval2.length)
#ConstructanewIntervalArrayfromIntervalobjects
array = pd.arrays.IntervalArray([interval1,interval2])
#DisplaytheIntervalArray
print("\nOur IntervalArray...\n",array)
#GettingthelengthofIntervalArray
#ReturnsanIndexwithentriesdenotingthelengthofeachIntervalintheIntervalArray
print("\nOur IntervalArray length...\n",array.length)输出结果这将产生以下代码-
Interval1... [50, 75] Interval2... [65, 95] Interval1 length... 25 Interval2 length... 30 Our IntervalArray... <IntervalArray> [[50, 75], [65, 95]] Length: 2, dtype: interval[int64, both] Our IntervalArray length... Int64Index([25, 30], dtype='int64')
